Exam 12: Using Basic Descriptive Analysis Performing Population Estimates and Testing Hypotheses

What does statistical inference take into account?

There are five basic types of statistical analyses that can be used by marketing researchers to reduce a dataset: descriptive analysis,inference analysis,difference analysis,association analysis,and relationships analysis.Under which circumstances is each type used?

A researcher asks the question: "On a scale of 1 to 5,how does Starbucks rate on variety of its coffee drinks?"Which of the following descriptive statistic would the researcher likely use?

Parameter estimation involves the use of three values.Which of the following is NOT one of the three values?

Marketing researchers often rely on the standard deviation when performing basic analyses,and never report it in their tables.

There are basic types of statistical analyses that can be used by marketing researchers to reduce a dataset.Which of the following is NOT one of those basic types of statistical analyses?

What is a measure of the differences of all observations from the mean,expressed as a single number?

A frequency distribution and mode are inappropriate for nominal scales.

The third measure of central tendency is the mean,sometimes referred to as the average.It differs from the mode and the median in that:

There are several guidelines in the presentation of hypothesis tests.Which of the following does not represent one of those guidelines?

Typically,the researcher works with several variables or questions in the survey that are related either by the research objectives or logically.

Regression analysis is not the method of choice used by the marketing researcher to understand complex relationship connections.

A researcher who wants to see if variables,such as advertising recall scores,positively associate with intentions to buy the advertised brand would use:

The hypothesized population parameter value can be determined using:

The mode is a relative measure of central tendency,for it does not require that a majority of responses occurred for this value.

Which of the following is a tabulation of the number of times that each different value appears in a particular set of values?

Computer statistical programs cannot distinguish the level of measurement of various questions.Consequently,it is necessary for the analyst to discern the level of measurement and to select the correct procedure(s).

With all hypothesis tests,the researcher should keep in mind that the ________ is the only source of current information about the population.

What is the degree of accuracy desired by the researcher and stipulated as a level of confidence in the form of a range with a lower boundary and an upper boundary?

A researcher asks the question: "About how many times did you buy fast food for lunch last week?"Which of the following descriptive statistic would he or she likely use?
